China Valve Packing Co., Ltd.

Magpie Valveis a leading manufacturer of industrial valves, packing, gaskets, and seal kits, driven by research and innovation. We are committed to advancing valve technology through cutting-edge material science, precision engineering, and performance verification by independent third parties.

At Magpie, we aim to redefine the role of valves in industrial systems by addressing the true determinants of reliabilitymost notably, sealing performance. While large-scale machining is no longer a primary hurdle in Chinas valve industry, the mechanical behavior of non-metallic materials, advanced sealing surface coatings, and friction and wear mechanisms remain critical challenges. These overlooked factors are at the core of our research and development efforts.

Our multidisciplinary team includes nuclear-grade sealing engineers, valve specialists, materials scientists, and electromechanical experts. Together, we bridge academic research with real-world application to create high-integrity valve solutions. We collaborate with top research institutions such as the National Key Friction Laboratory at Lanzhou University of Technology, the Ningbo Institute of Materials, East China University of Science and Technology, and the Shanghai Institute of Ceramics. These partnerships allow us to delve deep into low-leakage graphite sealing technologies and effectively address the root causes of sealing failure.

Magpie Valves product performance is rigorously tested and validated through third-party certifications. We proudly hold API 622, API 624, API 641, ISO 15848-1, TA-LUFT, and ISO 15848-1 CC3 certifications. Our valvesincluding gate, globe, and ball typeshave undergone comprehensive testing under extreme temperatures ranging from 400C to -196C and pressures up to Class 2500 LB. These efforts not only ensure compliance with global standards but also establish new benchmarks for safety, reliability, and innovation in the valve manufacturing industry.Know more about GoogleSEODirectory
